Solution

(a) Element 2 has a very low value of first ionization energy and a high value of second ionization energy. Hence, it is reactive alkali metal.
Its first ionization energy is lowest among the given elements.

(b) Element 4 has a second-highest value of first ionization energy among the given elements.
Hence, it is reactive non-metal.

(c) The element 1 has the highest value of first ionization energy among the given elements.
Hence, it is a noble gas

(d) Element 3 has the second-lowest value of first ionization energy among the given elements.
Hence, it forms a stable binary halide of the type AX2

Hence, the correct sequence is 2413.
